OIL-CUP- Specification of Letters Patent.

Patented Feb. 6, 1906.

Application filed larch 10, 1905. Serial No. 249,-!21.

To all whom it may concern:

Be it known that I, NATHAN SMITH, a citizen of the United States,residing at Stevensville, in the county of Queen Anne and State of Marland, have invented certain new and useful Improvements in Oil-Cups; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appcrtains to make and use the same. My inventionrelates to hand-oilers; and its ject is to )rovide a simple andinexpensive device of t is character having means by which the contentsof the oiler may be dischar ed in a steady stream and under considerable pressure and whereby the outflowing jet or stream can be projected asuitable distnnce, thus rendering the device articularly shown thepreferred adapted for use in discharging oi upon moving portions ofmachine to which access cannot be readily obtaine d i Another object isto combine in one part a flexible receptacle, drip-cup, and support,

With the above and other objects in view the invention consists of acontractible bulb preferably formed of rubber and having an outlet-tubedetachably connected thereto. A supporting-flange is formed integralwith the bulb and may be suitably reinforced to rotect it from wear. Adrip cup is also orrned integral with the bulb and is so disposed as toprevent oil or other liquid which may accumulate upon the tube fromflowin 7 down the sides and that portion of the bulb which is adapted tobe gripped in the hand of the operator.

The invention also consists of the further novel constructions andcombinations of parts hereinafter more fully described, and pointed outin the claim.

In the accompanfying drawings I have orms of my invention.

In said drawings, Figure 1 is a perspective view of the oiler. Fig. 2 isa vertical section therethrough,a ortion of the outlet-tube beingremoved. ig. 3 is a View, artly in elevation and partly in section, 0 amodified form of m oiler. Fi 4 is a section through a modifie form of oier, and Fig. 5 is a similar view of another modification.

Referring to the figures by numerals of reference, 1 is a bulb of rubberhaving a centrally-disposed annular bead 2 thereon and ed to be engagedby a shelf, box

provided at one end with a circplar flange 3, adapted to support thebulb in an upright sition. As shown in the drawings, t is flai e isprovided with a reinforcing-ring 4, pre erably formed of a hoop or ringof spring metal, which is seated within the flange and is adapted toprevent wear upon the flange. A tubular extension 5 is formed integralwith the bulb at its uppercnd,and the inner wall of. this extension isadapted to engage the threaded end 6 of an outlet-tube 7. This tube mabe of any suitable size andproportions. drip-cup S is formed integralwith the bulb 1, and consists of an inclined annular flange whichsurrounds the lower portion of extension 5. It will be obvious that thiscup will receive any liquid which may accumulate upon the tube 7 andflow downward thereon, thereby preventing the outer surface of the bulbfrom becoming oily.

In using this oiler the bulb l is compressed so as to expel most of theair therefrom, and after inserting the end of the tube 7 into the oilthe bulb can be released and by expand ing will draw the oil thereinto.When it is desired to discharge the oil, it is merely necessary tocompress the bulb, and as long as the same is subjected to pressure theliquid contained in the bulb Wlll be discharged through the tube 7 in asmall stream or jet which will be projected for a suitable distance.When the oiler is not in use, it can be supported in an upright positionby the flange 3. It will be understood that wear u on the flan e isrevented by the band 4. I desired, in ie'u 0? this band other weardevices may be employed. Moreover, instead of placin the tube 7 indirect engagement with the ulb the bulb may be secured to aninternally-threaded metal extensionQ, adapt the tube. I have shown thisconstruction in Fig. 3. The bulb may be permanently connected to theQXtGIISIOH by means of cement or can be held in engalgement therewith bycontracted pressure. he bead hereinbefore referred to-serves to hold thebulb-faces out of contact with the wall of or any other structure uponwhich the oiler may be placed, thereby protecting the faces of the bulbfrom in ury ghrough rubbing against an unyielding surace.

While I preferably form the body of the oiler as shown in Fi s. 1, 2,and3, I can, if desired, make said bo ies cylindrical, as shown at 10 inFig. 4, the up er portion of the body bein contracted an merging intothe. extension 11, about which the drip cup 12 is provided, or, ifdesired, the body of the oiler can be substantially frusto-conical inform, as shown at 13 in Fig. 5, the wall of the body being waved andmerging into its tubular extension 14. In either case the body is supported upon a flange 15, which is formed integral therewith ;and isprovidedwith a reinforcing ring 16, of spring metal, which is adapted toprevent wear upon the flange.

In the foregoing description I have shown the preferred forms of myinvention; but I donot limit myself thereto, as I am aware thatmodifications'ma be made therein without departing from the spirit orsacrificing the advantages thereof, and I therefore reserve the right tomake such changes as fairly fall within the scope of my invention.

Havin thus fully described my invention,

what I c aim as new, and desire .to secure by Letters Patent, is- A handoiler comprising a contractible, flexible bulb, an integral flangeextending from the bottom thereof and adapted to support the same in anupright position, a metalic ring embedded within the flange and havingone edge flush with the bottom of the flange, said ring constituting awear device, and an outlet-tube detachably connected to the top of thebulb, the bottom of said oiler being adapted to be forced inward atpoints surrounded by the ring.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

NATHAN SMITH.
